摘　　要：煤与瓦斯突出是威胁煤矿安全的重要灾害之一。煤与瓦斯突出矿井的突出危险性预测评估工作,对规范矿井生产、科学制定矿井瓦斯灾害防治措施、指导保证生产安全有着十分重要的意义。通过对煤的各项单项指标的测定(包括相对瓦斯压力、煤的破坏类型、煤的坚固性系数、煤样的瓦斯放散初速度),结合煤的初始释放瓦斯膨胀能指标对煤层的突出危险性进行综合性预测。Coal and gas outburst is one of important disasters of threatening the safety of coal mine, the work of coal and gas outburst dangerous prediction has the great significance, to regulate the mine production, scientific formulate mine gas hazard prevention measures and guiding the production safety. Based on determination of the single index, including relative gas pressure, damage types, rigidity coefficient, gas radiation, combined with the expansion energy, the outburst danger is predicted sythetically.

关 键 词：煤与瓦斯突出 瓦斯压力 瓦斯膨胀能
